An advertisement read aloud by a program host or presenter as part of the show, delivered in the host’s voice and often blended into the content so it feels like a personal recommendation. Investors care because these spots typically get higher listener trust and engagement than standard ads, can command premium rates, and create predictable revenue tied to a host’s popularity—while also concentrating risk if that host leaves or their reputation changes.
long-form host-read executionstechnical
A long-form host-read execution is an advertising spot in which a presenter or host speaks at length, often in their own voice, delivering a scripted promotional message about a product, service, or company. For investors it matters because these ads tend to create stronger audience trust and engagement—like a trusted friend’s recommendation—so they can drive greater customer response, higher marketing cost and stronger reputational or regulatory risk if claims are inaccurate.
dynamic adstechnical
Dynamic ads are digital advertisements that change their content in real time to match a viewer’s interests, past behavior, or current inventory—like a shop window that rearranges itself for each passerby. They matter to investors because they can increase sales efficiency and ad revenue by delivering more relevant messages, lowering customer acquisition costs, and producing clearer performance data that helps assess marketing ROI and forecast growth.
interactive motion-activated unitstechnical
Motion-activated interactive units are hardware devices that detect movement and respond with audio, video, lighting or touch-screen interactions to engage people in a location. Think of them like a self-starting display or kiosk that wakes up when someone approaches; investors care because these units can drive sales, measure customer interest, create recurring service or content revenue, and indicate how well a product or campaign captures attention.
controlled experimental designtechnical
A controlled experimental design is a testing method in which one group gets the treatment being studied and a comparable group does not, while all other conditions are kept the same so any outcome difference can be traced to the treatment. For investors, this provides clearer, more trustworthy evidence about whether a drug, device or business strategy actually works and is safe, reducing uncertainty about regulatory approval, market adoption and future revenue—like testing two cake recipes while changing only one ingredient to see which truly makes the cake better.
full-funnel impacttechnical
Full-funnel impact describes how an action, campaign or change affects every stage of a customer’s journey — from first awareness, to interest, to purchase and then to repeat use or loyalty. Investors care because improvements or declines at any stage can change future sales, marketing efficiency and customer lifetime value, so measuring the full-funnel impact is like checking a garden from seed to harvest rather than just one plant to understand long-term returns.

New study from Omnicom Media Intelligence and iHeartMedia outlines how evolving audio formats deliver measurable full-funnel impact
NEW YORK--(BUSINESS WIRE)--
A new Partner Intelligence study from Omnicom Media Intelligence - the research arm of global media management group Omnicom Media - and iHeartMedia finds that audio advertising is delivering measurable gains across awareness, trust, and conversion as innovations in format and creative are accelerating consumer action and deepening engagement.
The study - Turning Volume into Value: What New Audio Innovations Mean for Advertisers - is based on a controlled experimental design among more than 3,500 U.S. adults1 who listen to audio content weekly. It evaluates the effectiveness of standard audio ads alongside host-read, long-form, dynamic and interactive formats, providing marketers with a playbook for aligning audio strategy to specific business objectives.
With audio now accounting for roughly one-third of daily media consumption, the findings underscore its growing importance within the media mix and its ability to amplify performance across channels.
“Audio is one of the few channels that delivers both scale and intimacy,” said Lainie Fertick, President, iHeartMedia Insights. “When brands combine trusted human voices with thoughtful innovation, audio becomes a powerful driver of trust, engagement and accelerated purchase behavior.”
Audio delivers full-funnel impact - and amplifies other channels
Across formats, audio advertising drove significant lifts in core brand metrics, including a 22-point increase in unaided ad recall among in-market consumers, alongside gains in favorability (+5 points), search intent (+6 points), and purchase intent (+5 points). The research also highlights audio’s “multiplier effect,” demonstrating that exposure to audio ads improves responsiveness across social and digital channels, increasing engagement and branded search activity.
Trusted voices and long-form storytelling enhance credibility and accelerate conversion
Host-read ads emerged as particularly effective in building emotional connection and brand trust. Messages delivered by familiar or trusted voices generated stronger gains in brand relevance, search intent, and purchase intent than standard ads, reinforcing the influence of the listener-host relationship.
The study also found that trusted hosts accelerate decision-making. Exposure to host-read ads drove a 20-point lift in likelihood to purchase within a week, significantly outperforming standard ads.
Long-form host-read executions further amplified these effects. By allowing more time for storytelling, these formats delivered up to 2X higher recall than shorter ads and increased the likelihood of near-term purchase, making them especially effective for consideration and conversion objectives.
“Listeners develop real relationships with the voices they hear every day,” said Kara Manatt, EVP, Intelligence Solutions, Omnicom Media. “When brands tap into that credibility at scale, the impact is measurable - trusted voices don’t just influence perception, they drive action.”
Innovation in creative formats boosts relevance, engagement and action
Emerging formats are also expanding what audio can do for brands. Dynamic ads tailored to context - such as time of day or listener environment - improved perceived relevance (80% vs. 73% for standard ads) and delivered stronger lifts in search intent.
Interactive motion-activated units, which prompt listeners to engage directly, proved especially effective among younger and in-market audiences, generating incremental gains in both search and purchase intent. These formats transform passive listening into active participation, helping brands convert high-intent consumers more efficiently.
Beyond individual tactics, the study emphasizes the importance of sequencing formats strategically. Combining trusted host-read ads with dynamic and interactive elements enables brands to guide consumers from awareness through to action within a cohesive audio strategy.
